Microblade productions are a structuring element of the Upper Palaeolithic technical traditions of Northeast Asia that spread throughout an immense territory and accompany the Final Pleistocene settlements of Northeast Siberia. Yet, the functioning and the function of these microblades are little known. This paper presents the first functional data for the Upper Palaeolithic microblades of Eastern Siberia. It aims at investigating the technical purposes for which they were produced ca. 19 ky cal. BP ago in the Lower Vitim at the site of Kovrizhka IV, layer 6. This open-air site is multistratified and yields the earliest occupation layer of the North-Eastern Baikal region with the level 6 dated of ca. 19 ky cal. BP. Results show that microblades were both used as projectile inserts, probably fixed laterally, and as knife elements to cut soft materials. Faunal remains are rare and the osseous industry is absent from the archaeological record of Kovrizhka. This functional analysis therefore offers an indirect evidence of the repairing of the hunting equipment at the site and of the probable osseous or wood projectile points and knife handles to which microblades were hafted. At Kovrizhka IV, impact damage rates are low, notably because they include microblades that were not used as projectile inserts and microblades that were not used at all. In these cases, we could exclude the immediate consumption of the knapping products but hypothesize the constitution of a stock to replace damaged inserts. The concentration of microblades in the southern part of the dwelling of level 6 could therefore be partly interpreted as an area dedicated to the production and replacement of microblades into composite tools, including projectiles. The relatively flexible functioning of microblades seems to be common to other Upper Palaeolithic (Kashidawai I, Yoshiizawa, Hopyeong-dong, Ushki I) and Mesolithic sites (Pavlova I, Zhokhov) of Japan, Korea, Kamchatka, Northern and Eastern Siberia.
Dédier les 21e Rencontres Sabéennes à la mémoire de Rémy Audouin, décédé le 5 septembre 2016, s’imposait. Le nom de Rémy Audouin restera en effet invariablement associé au Yémen, à sa magie et à ses légendes. Pendant quarante années consacrées à ce pays magique, il fut parmi les premiers à découvrir les richesses des vestiges archéologiques de la civilisation du Yémen préislamique, « cinq fois millénaire » comme il le répétait souvent. Il était un défenseur hors pair et sincère du patrimoine yéménite.
Seigneur dans l’âme, généreux et humaniste, Rémy Audouin a tissé une amitié sans faille avec les Yéménites qui l’ont côtoyé. Grâce à sa gentillesse et à sa générosité, il a connu pratiquement tous les chercheurs s’intéressant au Yémen qui était si cher à son cœur. Comme premier administrateur du Centre Français d’Études Yéménites (l’actuel CEFAS) dont il a été l’un des fondateurs, il a su être d’une hospitalité et d’une générosité rare pour chacun. Il fut le premier sésame du Yémen pour de nombreux visiteurs et savants qui découvrirent ce pays dans les années 1980. Archéologue, artiste, esthète et amoureux de l’humanité, de la vie et du soleil, tous ceux qui ont eu la chance de le rencontrer ont été touchés par son intelligence, sa connaissance des sites et de l’histoire du Yémen, et par sa douceur et son rayonnement intérieur et extérieur.
La disparition de notre collègue et ami Rémy, Râmî comme l’appelaient les Yéménites, marquera malheureusement la fin d’une période faste pour la recherche. Elle coïncide tristement avec la chute de l’État du Yémen, l’abandon de sa population et avec la destruction de son patrimoine archéologique et his- torique qu’il a si bien valorisé, exposé et défendu.
Nombreux ont été les collègues, les amis et les proches de Rémy qui ont voulu exprimer dans cet ouvrage leurs hommages, leur amitié et leur affection. Certains l’ont fait à travers des contributions scientifiques, d’autres à travers des œuvres d’art, des souvenirs et des rencontres plus personnelles.
Que la présence de tous ces témoignages puisse contribuer à faire vivre en nous le souvenir de cet être si cher et de son importante contribution à la recherche archéologique yéménite. Que notre mémoire se réjouisse chaque fois qu’elle croisera sa prestance, sa noblesse de vue et son infatigable tendresse pour les autres.
Avec tous les amis et collègues de Rémy Audouin, nous expri- mons ici notre profonde tristesse, notre amitié, ainsi que notre affection à sa famille et à ses proches. Nos pensées vont tout particulièrement à notre amie et collègue, son épouse Marylène Barret-Audouin qu’il appelait ‘la divine’ et qui, avec l’amour du Yémen en partage et beaucoup de courage, a contribué à la réalisation de cet ouvrage.

Microcomputed tomography is a valuable tool for studying ancient ceramics technology. Analysing pottery 3-D images is a challenging issue, the data being extremely noisy and heterogeneous. Quantitative criteria are introduced for the characterisation of a previously unrecognised pottery building method, the Spiralled Patchwork Technology (SPT). An analytical protocol has been implemented that applies to 3-D reconstructions of ceramic sherds and integrates automatic segmentation of porous systems and shape recognition using Hough transform. It enables discriminating between SPT and other techniques for vessels manufacture, and opens up many perspectives for independent characterisation of ancient technical gestures in ceramic technology.

Marine Isotope Stage 6 (MIS 6; ca. 185–135 ka) is the penultimate glacial stage and constitutes the end of the Middle Pleistocene. This glacial period is typified by generally cold and dry conditions in the western Mediterranean region. Despite the relatively large number of pollen and speleothem studies of MIS 6 in this region, the number of MIS 6 archaeological sites is low. Lazaret cave, situated at 26 m a.s.l. in the city of Nice in southern France, contains an archaeological sequence (layers CII inf. to CIII) dated to MIS 6. We present a multi-method approach using the small-vertebrate assemblages (mainly rodents and herpetofauna) from the entire sequence to characterize the climate and the environment of the site. The Mutual Ecogeographic Range, the Bioclimatic Model andthe Quantified Ecology methods, as well as the Taxonomic Habitat Index, Climatograms and the Simpson Diversity Index were used to reconstruct the palaeoenvironmental and palaeoclimatic conditions. The results suggest a generally cold climate with a relatively humid environment and a landscape dominated by deciduous temperate forests. The findings are consistent with the general trends reported from other proxies (large mammals, birds and marine gastropods) studied at Lazaret cave, other MIS 6 sites in the Mediterranean region with small vertebrate studies and the general trends shown by marine cores, terrestrial pollen sequences and speleothems from western Europe. Given the scarcity of data for MIS 6 archaeological sites, Lazaret cave constitutes an important site for our knowledge of the climate and the environment of this period.

During the Last Interglacial-Early Glacial transition (MIS5-MIS4; ~73 ka), substantial hydroclimatic changes affected morphogenetic processes, landformdynamics, and ecosystem variability over the Mediterranean sub-alpine valleys. This transition is mainly preserved in the northern Mediterranean region in continuous marine, lacustrine, and peat bog archives. To understand better local-to-regional hydro-sedimentary processes, their climatic significance, and their direct impact on prehistoric settlements, this manuscript reinvestigates a known continental sedimentary record with revised methods. The Middle Palaeolithic site of La Combette in the western Provence region (southeastern France) presents a thick sedimentary key sequence for studying environmental changes from the MIS5 to the MIS3. A review of previous studies with the integration of new micromorphological, sedimentological, physicochemical, malacological, and luminescence ages allows us to characterize the sedimentary processes and environmental patterns during this major climatic transition. Alternating warm and cold conditions and shifting vegetation patterns reflect the strong environmental instability of the end of the Last Interglacial Period. The emergence of a steppe-like ecology dominated by cryo-turbated loess deposition marks the beginning of the Early Würmian Glacial period (MIS4-MIS3; ~73 ka to ~50 ka), contemporaneous with the last Neanderthal occupation at La Combette rock shelter. Comparisons with regional palaeoclimatic data allow us to detail local climatic settings and provide evidence of divergences with larger-scale quantitative reconstructions during a period of significant environmental and socio-cultural shifts.
Abstract
Runoff farming is a key hydro-agricultural strategy that has proven efficient in arid areas. Research in Arabia on the function, development, maintenance, durability and abandonment of this technology is scarce. A multiproxy investigation (cartography, sedimentology, pedology, geochemistry, paleo-ecology and chronology) was conducted on a recently abandoned terraced area in Rustaq, Northern Oman. The aim was to characterize the formation, function and management of this runoff system and the driving factors behind its success. Cycles of cultivation were identified during the Iron Age II/III periods (specifically 750–450 BCE), the Early Pre-Islamic Period (PIR) (specifically 350–200 BCE), the Early and Middle Islamic periods (specifically 8–10th C CE, 13th-14th C CE) and the late Islamic period (specifically 17th C CE and later). This expansion and perenniality was possible thanks to: 1- available water (local to micro-regional orogenic precipitation despite a regional aridification during these periods); 2- suitable soils (weathered geological outcrops, probable aeolian /dust particles); 3- a system of production combining crops and husbandry; 4- a progressive increase in agricultural specialization (crops grown and techniques) in parallel with a diversification in hydraulic technology. These results are to some degree in accordance with known phases of settlement intensification and economic growth, but also reveal the persistence of small-scale rural livelihoods during periods of harsh conditions for which archaeological traces are very scarce.

This book brings together 30 papers by leading scholars in the field of usewear and residue analysis. This publication aims to revive the debate on the role of traceology (use-wear and residues) in multidisciplinary approaches that address archaeological questions. Many studies on technological aspects of material culture deal with specific material categories (e.g. flint, ceramics, bone), often in separate or isolated ways, and this division does not really reflect the integrated nature of technical systems in which different material categories are in dynamic interaction.
Hence, exploring the interaction between different chaînes opératoires is crucial for a more global concept of the toolkit with all its components and it is a precondition for paleo-ethnographic reconstructions of technical systems and economies. Starting from a functional perspective, the papers in this book explore various topics such as apprenticeship, group dynamics, social status, economy, technological evolution, spatial organization, mobility patterns and territories, or adaptations to cultural and environmental changes.
This collection of papers, presented at the AWRANA conference in 2018, constitutes a major sign of the dynamism, popularity and scientific importance of our discipline in current archaeological research. AWRANA 2018 was dedicated to the memory of H. Keeley.

Valle Giumentina est un gisement des Abruzzes du Paléolithique ancien et moyen de plein air, connu grâce aux travaux approfondis des années 1950 menés par le préhistorien A.M. Radmilli et le géographe J. Demangeot1. Sept horizons archéologiques avaient été mis au jour au sein d’une séquence sédimentaire formée de sédiments lacustres et de plusieurs paléosols, en bordure d’une ravine profonde ayant incisé les dépôts pléistocènes.

Oasis soils result from the combined action of natural and anthropic processes, and thus constitute valuable systems for the understanding of human–environment trajectories over the millennia. The present research aims to develop the study of ancient oasis soils by identifying proxies to detect past agricultural practices. Ten reference pits were dug in Masafi, in both cultivated plots (irrigated plots with palm trees/fruit trees/cereals; manure/ashes/carbonates) and abandoned ones. Bulk sediment samples were analysed for geochemistry/pedo‐sedimentary studies: inductively coupled plasma‐optical emission spectrometry, loss on ignition, pH, electrical conductivity, grain size and magnetic susceptibility. This multiproxy approach enabled the creation of a soil typology of oasis agricultural modes. Irrigation and liming lead to salinisation, particularly in a B‐horizon. Manure creates a hortic horizon, enriched in P and Zn. Ashes can be detected with a simultaneous increase of magnetic and salinity values. Soils in plots with fruit trees/cereals are not distinguishable from those with palm monoculture. Weathering was identified on the basis of the enrichment in Al, Ti, K Na, Ni, Cr and Fe, whereas proxies of ancient practices seem to be preserved after 15 years of abandonment. As leaching processes appear to be limited to the first 50 cm, the durability of soil signatures depends on how they were buried.
